Is it just alcohol talking OR does he want to break up ?

Ive written several times about my boyfriend who is letting me down.
I LOVE him so much, but now he is driving me away.
long story short:
dating for 9months . he lives 2-3 hours away, i am moving to his city (ill live on my own) March 1. I have a
lot to keep me busy there and friends of my own.

he started to change in october.
ive recently pieced things together and see that he isnt treating me well enough or cherishing me

1. started talking to two girls he used to date.
1 is a rich french-iranian lawyer and the other is a rich russian-iranian. both very attractive and the french iranian is super skinny like he likes. (shes size 00, im size 6)

he claimed theyre just friends.
but one of them he took to a friends party back in October and the friend said she was hanging all over him...

since that party he has invited me to halloween, thanksgiving, his office christmas party,
christmas at his parents and new years eve and my birthday.
so we went spent a TON of time together since he took her to one party.
but during that time he also started writing the french-iranian woman again, but didnt tell me until he was very drunk on nye.......



2. he has stopped telling me im attractive or being sweetly affectionate. we still have fun hanging out, but
he will often call me a 'crazy redhead'. a name he knows i find insulting.
he just doesnt seem to care if he is annoying me.

3. he acts jaded about relationship and marriage.
he wasnt this was way for a long time.
here is the thing that has upset me the most ***************
Last night he called me and when i told him his brother (who is a very close friend of mine) has found a new girl he is a serious about he replied that he "hopes his borther doesnt fall into the monogamy ditch"
**** ouch
he is 36 years old and we have been friends for two years BEFORE dating. during most of that time he told me how he wanted marriage and kids.
i dont know what changed.

4. he starts talking about other women's bodies on tv and online when we're together.
he also made some joke about how sex with 22 year olds is best when he was drunk (im 33)
he then backtracked and said he meant his younger bro says that. uh huh
also we have had oral sex, but NOT sex yet.
so when he made th ejoke about having sex with 22 year olds is best, i got very disturbed.
he knows im old fashioned about sex.......


5. when i joked and asked if something made him jealous, he says no he couldnt be made jealous nowadays.

leave him fast ?
